piston, and has for its objects to provide al comparatively simple, inexpensive device of this character wherein the water will be lifted both upon the upward and downward stroke of the piston, and one wherein the water will be forced in a continuous stream upward through the stand-pipe.

llilith these and other objects in view, the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanyingdrawings: Figure 1 is a vertical section, taken centrally and longitudinally through a pump embodying the invention and showing the piston in its upward position or stroke. Fig. 2 is a similar view showing the piston on its down stroke.

Referring to the drawings, l designates the pump barrel or cylinder connected at its upper end upon and for communication with the lower end of a stand-pipe 2, there being provided at the lower end of the cylinder an inlet port 3 adapted for communication with the lower end of an intake pipe 4 disposed centrally in and extended partially through the cylinder 1, while fixed upon the upper, open end of the pipe 4, which is provided adjacent its upper end with an annular series of openings or passages 5, is a head 6 having a marginal groove in which is arranged a rubber or other packing gasket 7.

Mounted for reciprocation in the cylinder 1 is a duplex pumping piston comprising a cylindrical tubular body portion S, in which the head 6 fits, and end heads 9 and 10 provided respectively with openings or ports l l, 12, and of which the head 9 is engaged with the lower end of a pumping rod 13 extended upward through the stand-pipe 2, while the head 10 is provided with a tubular neck 1/-1 formed to 'fit and slide upon the intake pipe 4, there being mounted on the rod 13, which is provided with a stop or abutment 15, a movable valve 16 adapted for closing the ports 11, a similar valve 17 adapted for closing the p ortsil 2 being inovably mounted on the neck 1-1 onto the outer oilower end of which there is tapped a nut 1S constituting a stop for limiting the opening movement of the valve.

Arranged above the head 6 for closing the upper open end of the intake pipe 4L is a valve 19 connected by members or bolts 20 cX- tended through suitable openings in the head with a valve 21 arranged to slide on the pipe 4 and for closing the openings 5, it being understood, of course, that the connecting members 20 are susceptible of sliding movement in the openings in the head to permit of alternate movement of the valves 19 and 21 to open or closed position.

In practice, during reciprocation ofthe piston 8 and upon its outstroke the valve 16 will close the ports 11 and the valve 17 move to open position, while at the same time the valve 19 will move to open position and valve 21 to position for closing the passages 5 whereby water will be drawn upward through the intake pipe Ll and delivered into the upper portion of the cylinder 8 above the head 6, while at the same time the water previously delivered into the lower portion of the piston body S below the head 6 will be forced outward through the ports 12 into the pump cylinder 1. On down stroke of the pumping piston the valve 17 will move to closed position and the valve 16 to open position, while at the saine time the valve 19 will close and valve 21 open, whereby the water will be drawn upward through the intake pipe 4 and pass through the o peiiings 5 into the lower portion of the piston body S below the head 6, the water in the upper portion of the piston body being at the saine time discharged through the openings 11 into the pump cylinder l. During either stroke of the pumping piston water in the cylinder 1 will be forced upward through the stand-pipe 2, thus insuring the delivery of the water in a continuous stream through said pipe to the ump.

Having thus described my invention, what I claim is:

In a pump, a barrel, a stand-p ipe communicating therewith, an open ended intake pipe sustained in and extending partly through the barrel, a pumping piston arranged for reciprocation in the barrel and comprising a tubular body portion having end heads provided with ports, a head fixed on the intake pipe and fitted within the tubular body portion of the piston, the intake pipe being pro- IOO slidably mounted in the fixed head and oonvided With transverse ports at a point adj a- I nesting the last named yalves for alternate Io cent the head, movable valves sustained for movement to4 open or closed position. alternately closing the ports in the heads of In testimony whereof7 I affix my signature tle pumping piston durilcllg reeiproeationdof in presence of two Witnesses.
